Stayed here for one night in April. The place looked a bit deserted when I arrived and there is not too much life on the doorstep (although the lively beach village is just a ten minute walk away)... A dorm bed was inexpensive but not the nicest or cleanest I have ever stayed in and overall the place struck me as a bit quiet and lacking atmosphere...

Good points were the friendly staff; free computers and, as mentioned, the price...if you're after a bit of peace and quiet this might be the place for you but otherwise maybe stick to the Chaweng region

i stayed at monkey samui for 4 nights at 300 baht for a female dorm.
it was the cheapest thing i could find for the christmas period with vacancies.
i initally thought i'd made a bad choice, location is not so good unless u hire a bike there your about 15min from Chaweng beach, the main party area on Samui.
But the place was clean, friendly, inviting and run by 3 very helpful men.
i would highly recommend staying here as it was so peaceful quite and amazingly friendly :)

I didn't have any expectation when I first booked the room at Monkey Samui Hostel. I chose the place coz it was cheap and easy access from the airport as I have traveled to Samui before and know how the local transportation can be very a nightmare. The place turned out to be a nice little hostel with quiet atmosphere which is a very nice change after all the parties the night before. The bathroom was clean. The bedroom is airy. There was a kitchen to cook your food if you are in the cooking mood and lots of DVDs to choose from. All and all this is a nice little hostel for people who want to have a good rest after the wild night at full moon party!!!
